DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 is a schematic block diagram of a mobile communication apparatus 100 according to an embodiment of the present invention. The mobile communication apparatus comprises a processor 102, a user interface 104, and a transceiver 106. The user interface 104 and the transceiver 106 are connected to and controlled by the processor 102. The processor is arranged to perform, in conjunction with the user interface 104 and the transceiver 106, a plurality of functions, which are normally performed in a mobile communication apparatus. However, to not obstruct the special features of the present invention, description of these normally performed functions are omitted in this disclosure.

The mobile communication apparatus is capable of presenting themes. A theme in a mobile communication apparatus is a feature used to provide a preferred appearance to a user interface layout. A theme can affect characteristics of a layout, background color, fill and border characteristics of a field, as well as text attributes for labels and/or text. A mobile communication apparatus capable of presenting themes normally provides a set of themes which the user can select according to her preferences at the moment. However, in the present invention the layout of the user interface according to the themes is extended to the audio domain, as will be described below.

The processor 102 is arranged to generate an audio signal in response to a theme, which can be set directly by a user, or by an application executed on the apparatus. Further, the theme can be set by a received message comprising information about which theme to set, or the entire characteristics of a new theme to be set. The theme can also be set in correspondence to a contact associated with an action performed by the apparatus, e.g. a contact accessed by the user in a contact database (not shown) of the apparatus 100, e.g. a phone book, or an incoming or outgoing phone call or message from/to a person associated with an item in the contact database.

The audio signal can comprise a speech signal, which can be generated by text to speech conversion or by voice manipulation, which is performed by the processor 102. The theme includes voice characteristics for speech of the speech signal. For example, when a certain person associated with a contact item calls, a certain theme is set, which comprises voice characteristics, e.g. the particular characteristics of a cartoon character, wherein the name in the contact database is output through text to speech conversion and with a “cartoon voice”, and then can either incoming or outgoing speech signal, or both, of the phone conversation be voice manipulated to sound like the cartoon voice. Another example is a received text message from a person associated with a contact item associated with a theme comprising the voice characteristics of a science fiction character, wherein the text message is converted to speech with the science fiction voice characteristics, and the message is output as speech through the user interface 104. Any combination of the above described features can be set in the themes. According to an embodiment of the present invention, it is also possible to send the audio signal and/or the theme to another subscriber, or to a server in a telecommunication network. For example, a text message to be sent or received can comprise a tag related to text to speech by certain voice characteristics, such that a given voice style can be reproduced. Also other audio features than speech and voice styles can be employed within the audio theme concept, and theme management depending on other parameters. A theme can be activated by a timing signal, e.g. provided by a clock or calendar in the apparatus. For example, when a call is performed when the calendar indicates out of office or vacation, the sound of seagulls and waves can be introduced as a background sound, or when a message is received, comprising a tag indicating that the sending person is in a meeting, a huge sigh is played. The concept of themes tied to association with a contact item is here described in relation to themes comprising audio. However, the concept of themes tied to association with a contact item can be utilized for any theme, e.g. presenting visual effects, background colors or images, adapting applications, etc., when reading messages from a particular contact, viewing calendar events which includes the contact, playing games with the contact, talking to the contact, chatting with the contact, etc.

A system architecture for managing a system 200 according to an embodiment of the present invention is shown in FIG. 2. A Home Location Register (HLR) 202 contains a database (not shown) including relevant subscriber information for provision of telecommunication service. A CCITT specified network 204 interconnects the individual parts of the system 200. A theme gateway 206 is a switching unit routing a theme message to a mobile communication apparatus 208-212. A Theme Service Center 214 (TSC) and the theme gateway 206 handles and routes the theme messages between the TSC 214 and the network 204. From the network 204, the theme messages are routed to the mobile communication apparatuses 208-212 via a Mobile Switching. Center (MSC) 216 to a Base Station Controller (BSC) 217 and a Base Transceiver Station (BTS) 220, 221, or a Radio Network Controller (RNC) 218 and a Node B 222. Alternatively, the theme messages are routed to the mobile communication apparatuses 208-212 via a Serving GPRS Support Node (SGSN) 226, 228 to the BSC 217 and the BTS 220, 221, or the RNC 218 and the Node B 222, respectively. The BTS 220, 221 or the Node B 222 establish the air connection to the mobile communication apparatuses 208-212.

According to an embodiment of the present invention, a network operator or other third party company handling a theme server 224 could offer a theme provision function. For example a network operator may have a theme server 224 supporting a feature where the theme provider may provide themes and the users may send a theme request from their mobile communication apparatuses 208-22 to the theme server 224. This theme server 224 automatically may place people sending a similar request to the theme server 224 into “theme groups” or “theme rooms”. Further, themes in the theme server can be created or edited by any of the users of the theme group or members of the theme room according to a special service, where a user or member send a message comprising theme characteristics to the theme server 224.
